title: Experimental broadband absorption enhancement in silicon nanohole structures with optimized complex unit cells.
abstract: We design silicon membranes with nanohole structures with optimized complex unit cells that maximize broadband absorption. We fabricate the optimized design and measure the optical absorption. We demonstrate an experimental broadband absorption about 3.5 times higher than an equally-thick thin film.
